Pushing back hard at a new ad by political opponents, Vice President Joe Biden and former President Bill Clinton accused the Mitt Romney campaign Monday of saying "absolutely anything to win" and engaging in an attack on President Obama's auto industry record that is "the biggest load of bull in the world."

The tough rhetoric comes after the Romney campaign launched an ad in Ohio claiming that ""Obama took GM and Chrysler into bankruptcy and sold Chrysler to Italians, who are going to build Jeeps in China."

Speaking to over 4,000 supporters in Youngstown, Clinton flatly decried that as "bull."

"It turns out, Jeep is reopening in China because they've made so much money here, they can afford to do it and they are going on with their plans here," he said. "They put out a statement today saying it was the biggest load of bull in the world that they would ever consider shutting down their American operations. They are roaring in America, thanks to people like the people of Ohio."

Biden, whose stump speech was even more littered with folksy appeals than usual as he shared the stage with Clinton, accused Romney of "pirouettes more than a ballerina" on his auto industry stances and called the ad "an absolutely patently false assertion."

"Ladies and gentlemen, have they no shame!?" he added. "I mean, what? Romney will say anything, absolutely anything to win, it seems."

Obama's record on the auto industry bailout is largely credited for buoying his poll numbers in swing state Ohio, a firewall Romney is eager to burn through.

Biden on Monday also accused Romney of proposing to "liquidate" the auto industry, a claim that the GOP nominee vigorously contests.

“Today, Vice President Biden falsely claimed that Mitt Romney wanted to ‘liquidate’ the auto industry, and was dishonest about the administration’s own record," said Romney spokesman Ryan Williams. "Mitt Romney’s support for loan guarantees and warranties for the U.S. auto industry is clear. The Obama campaign is less concerned with engaging in a meaningful conversation about his failed policies and more concerned with arguing against facts about their record they dislike."
